Drupal Core - Moderately Critical - Multiple Vulnerabilities - SA-CORE-2016-002

Saving user accounts can sometimes grant the user all roles (User module - Drupal 7 - Moderately Critical)

A vulnerability exists in the User module, where if some specific contributed or custom code triggers a rebuild of the user profile form, a registered user can be granted all user roles on the site. This would typically result in the user gaining administrative access.

This issue is mitigated by the fact that it requires contributed or custom code that performs a form rebuild during submission of the user profile form.

Views can allow unauthorized users to see Statistics information (Views module - Drupal 8 - Less Critical)

An access bypass vulnerability exists in the Views module, where users without the “View content count” permission can see the number of hits collected by the Statistics module for results in the view.

This issue is mitigated by the fact that the view must be configured to show a “Content statistics” field, such as “Total views”, “Views today” or “Last visit”.

The same vulnerability exists in the Drupal 7 Views module (see SA-CONTRIB-2016-036).
